A Brief History of the 38 Super Auto
The origins of the .38 Super Auto can be traced back to the early 20th century. It was developed as an improved version of the .38 ACP (Automatic Colt Pistol) cartridge, aiming to enhance its performance and stopping power. The cartridge was designed to provide shooters with a more potent option for self-defense and target shooting.
The .38 Super Auto gained recognition for its use in early semi-automatic pistols, particularly the Colt Model 1911. Its popularity soared during the 1930s and 1940s, as it became a preferred choice for law enforcement officers and civilians seeking a reliable and effective self-defense round.
Performance and Characteristics
The .38 Super Auto cartridge boasts impressive performance characteristics. It is known for its high velocity and flat trajectory, making it an excellent choice for long-range shooting. The cartridge's design allows for efficient utilization of powder, resulting in increased muzzle velocity and improved accuracy.
One of the standout features of the .38 Super Auto is its ability to handle a wide range of bullet weights and types. Shooters can choose from various options, including full-metal-jacketed (FMJ) rounds for target practice and self-defense, as well as hollow-point or expanding bullets for increased stopping power.
Ballistics and Trajectory
The ballistics of the .38 Super Auto are impressive, offering shooters a flatter trajectory and increased accuracy over longer distances. With a typical muzzle velocity of around 1200-1400 feet per second, the cartridge delivers a substantial impact, making it suitable for various shooting disciplines.
The following table provides a comparison of the .38 Super Auto with other popular pistol cartridges:
| Cartridge | Muzzle Velocity (ft/s) | Muzzle Energy (ft·lbf) |

Choosing the Right 38 Super Auto Pistol
When selecting a .38 Super Auto pistol, several factors come into play. Here are some key considerations to help you make an informed decision:
Frame Size and Ergonomics
The frame size of the pistol should be comfortable and suitable for your hand size. Look for models with ergonomic designs that provide a secure grip and reduce recoil. A well-designed grip can enhance accuracy and control during shooting.
Action Type
The .38 Super Auto is commonly found in both single-action and double-action pistols. Single-action pistols require the hammer to be cocked manually before each shot, offering a crisp trigger pull. Double-action pistols, on the other hand, allow for both single-action and double-action firing, providing versatility and ease of use.
Barrel Length
The barrel length of a .38 Super Auto pistol can vary, typically ranging from 3 to 5 inches. Longer barrels generally offer increased accuracy and velocity, making them suitable for competitive shooting. Shorter barrels are more compact and concealable, making them a popular choice for concealed carry.
Magazine Capacity
Magazine capacity can vary depending on the pistol model and its intended use. For self-defense, a higher magazine capacity can provide added peace of mind. However, for competition shooting, a lower capacity may be preferred to comply with specific rules and regulations.
Ammunition and Reloading
The versatility of the .38 Super Auto extends to its ammunition options. Shooters can choose from a wide range of factory-loaded ammunition, offering various bullet weights and types to suit their needs. Whether it's target shooting, self-defense, or competition, there's an option available.
For those interested in reloading, the .38 Super Auto cartridge provides ample opportunities for customization. Reloading allows shooters to fine-tune their ammunition to achieve specific performance characteristics, such as increased velocity or improved accuracy.
Common Bullet Types
- Full Metal Jacket (FMJ): Ideal for target practice and training, FMJ bullets provide consistent performance and accuracy.
- Jacketed Hollow Point (JHP): Designed for self-defense, JHP bullets expand upon impact, increasing their stopping power.
- Semi-Jacketed Hollow Point (SJHP): A middle ground between FMJ and JHP, SJHP bullets offer a balance of accuracy and controlled expansion.
Shooting Techniques and Training
To get the most out of your .38 Super Auto pistol, it's essential to develop proper shooting techniques and engage in regular training. Here are some key aspects to focus on:
Grip and Stance
A solid grip and stable shooting stance are fundamental to accurate shooting. Ensure your grip is firm yet relaxed, with your fingers positioned correctly on the trigger. Maintain a balanced stance, with your feet shoulder-width apart, to provide a stable foundation for shooting.
Trigger Control
Mastering trigger control is crucial for consistent and accurate shooting. Practice smooth, deliberate trigger pulls, avoiding any jerking or anticipation. Focus on maintaining a steady sight picture and trigger squeeze to achieve precise shots.
Breath Control
Breath control plays a significant role in shooting accuracy. Take a deep breath before each shot, exhale slowly, and hold your breath momentarily as you squeeze the trigger. This technique helps stabilize your body and reduces the chances of flinching or jerky movements.
Competitive Shooting with the 38 Super Auto
The .38 Super Auto has gained immense popularity in competitive shooting disciplines, such as IPSC (International Practical Shooting Confederation) and USPSA (United States Practical Shooting Association). Its combination of power, accuracy, and versatility makes it a top choice for shooters looking to excel in these fast-paced and dynamic sports.
Competitive shooters often fine-tune their .38 Super Auto pistols to achieve optimal performance. This may involve custom barrel and trigger work, as well as the use of specialized ammunition designed for competition shooting.
Conclusion
The .38 Super Auto cartridge offers shooters a powerful and versatile option for a wide range of shooting disciplines. With its impressive performance, flat trajectory, and customizable nature, it has earned its place as a favorite among shooting enthusiasts.
